1/4 HP, Série V7

Le V7 était un lecteur compact à faible coût et haute performance, utilisable en mode V / f ou Open Loop Vector. En plus d'une bonne régulation de la vitesse, la commande vectorielle en boucle ouverte fournissait également un couple plus élevé à des vitesses plus basses. Le V7 était idéal pour les applications telles que les convoyeurs, les broyeurs, les centrifugeuses, les pompes, les ventilateurs, les soufflantes, les machines-outils, l'emballage, le traitement des aliments et la buanderie commerciale.
